| Criterion |  Architecture SAAM (Software Architecture Analysis Method) |  Architecture Architecture Decision Record |  Architecture Architecture Inception Canvas |  Architecture arc42 |
|---|---|---|---|---|
Purposedifferent | SAAM helps teams judge an architecture’s suitability for selected tasks and changes. It is particularly useful for examining modifiability and comparing architecture alternatives with clear reasoning. | An ADR permanently records an architecture decision with context, trade-offs, and consequence. It creates continuity for later changes because the decision path stays traceable. | The Architecture Inception Canvas bundles the first architecture questions into a compact decision picture. It fits when an initiative is still in motion but still needs clear guardrails. | arc42 structures architecture knowledge so teams can document system, decisions, and risks consistently. The template builds a living understanding of the architecture instead of scattered notes. |
Complexitydifferent | High | Low | Low | Low |
Timedifferent | Preparation, scenario analysis, and findings review; effort depends on scope | 15-45 min | 1-2 h | 1-2 Tage |
Participantsdifferent | Architecture experts and stakeholders for scenarios and weighting | 1-3 | 3-8 | 1-4 |
Formatdifferent | Workshop + async | Async | Workshop | Workshop + async |
Outputdifferent | Domain functions mapped to components and connections, Quality attributes and evaluation criteria, Typical tasks and their effects on the architecture, Reasoned evaluation or comparison of alternatives | ADR File, Decision Log, Rationale | Inception Canvas, Risks, Goal List, Open Questions | Architecture Document, Context View, Runtime View, Deployment View |
